I'll ask three questions:
How much do you shoot?
How much time do you have?
If shooting cost less would you shoot the same or more?
A hunter who fires five shots a year won't profit from reloading. A busy, three-job family guy won't have time to either reload or shoot.
If cost of factory ammo keeps you from shooting or shooting more, and you have spare time, reloading is an option.
Caliber is also a factor. With some calibers (like 9mmP) dirt cheap, it does not pay to reload or even worry about reloadable cases. With, say, .44 Magnum, reloading is almost necessary if you want to shoot much and are not wealthy.
